Integrins are receptors that facilitate cell-extracellular matrix (ECM) adhesion. Several types of integrins exist, and one cell may have multiple different types on its surface. Integrins are found in all animals. And total 16 integrins were found in vertebrates so far. We provide a complete integrin binding peptide array to help researchers to quickly identify the types of integrins on the cell surface. Ligands for integrins include fibronectin, vitronectin, collagen and laminin.
